great, now it works... thank you!

A short example:

\documentclass[pdftex,a4paper]{scrreprt}
\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage{color}
\usepackage[formats]{listings}
\definecolor{darkred}{rgb}{.5,0,0}
\definecolor{darkblue}{rgb}{0,0,.5}
\lstnewenvironment{R}
{
\lstset{
basicstyle=\ttfamily,
frame ...

I don't know why, but none of these solutions work... I also tried escapechar:
I am using two languages (SAS and R) and the escapechar only worked for SAS, in R it says "undefined control sequence".

So I've defined a new environment for R:

\lstnewenvironment{R}
{
\lstset{
basicstyle=\ttfamily ...

unfortunately not better...

i don't understand, why you use tabsize= twice in lstset{}

And why do you need escapeinside={\%*}{*)}?
("Now all weird tildes will be replaced automatically in all of your code. Forget escape characters etc, this is all you need!")

Thanks!

Thanks stinkinrich88!

It solves my tilde problem too, but now tabsize=4 doesn't work anymore:

\lstset{ breaklines=true, % new line
basicstyle=\ttfamily,
tabsize=4}

\begin{lstlisting}[language=R, format=tilde]
...
\end{lstlisting}

output looks like tabsize=0
